Introduction

Today, we can't pass custom property to any React Native Component like View, Image. And if we do that, React Native will throw errors.

Details

There are 3 primary situations we need this feature:

1. We are building a debug tool like React Developer Tools, so we need a custom protocol/property to display/design the interaction/information with the debug tool.

2. We are commutating/transferring data with the native(Android/iOS) , so we need a way to define and transfer the data on the component instance.

3. We are traversing the fiber tree and do something like track/report events to the server, so we need a way to get the data.

Discussion points

Like Web/DOM, it provides a way(data-xxx) to define your custom property and React supports that naturally. But in React Native, there is no way like that. I hope we can support it too, thanks.
